Myoelectric prostheses were reported to be practical and effective by Hermansson et al. based on their myoelectric prosthesis usage survey of myoelectric prosthesis users (n=75) [1] . Moreover, there are reports affirming that myoelectric prostheses play an important role in achieving rehabilitation goals [2] [3] [4] . However, this previous research involved survey-based retrospective studies. Therefore, while these studies support the usefulness of myoelectric prostheses, their findings are

Furthermore, Resnik reported that the effects of myoelectric prosthesis training on the ability of amputees to operate upper limb prostheses are unclear [5] . Hence, it is necessary to clarify the effects of myoelectric hand operation training based on objective data. Myoelectric prosthesis operation training was proposed by Atkins in 1992 [6], and associated guidance was formulated by Johnson et al. in 2015 [7]. The training was organized into single-handed and dual-handed tasks, and it was recommended that dual-handed tasks should be performed after practicing single-handed tasks [6, 7] . However, there are no objective data to verify how single-handed and dual-handed tasks affect amputees' ability to operate myoelectric prostheses. The
